So far I'm liking MIR. Used as a plug-in in Logic, my session volume is about 12 db quieter than my pre-MIR sessions. I see I can compensate partially by raising the volume on each channel by 6 db, but I'd rather not lose my headroom if I have to make tweaks later on. There's a volume offset slider on MIR's main output, but it grayed-out, and it too only can add 6 db.
I know I can always add a Gain plug-in in Logic, but is there something I'm missing? Thanks.
Hi Gary,
a few words of background information ex ante:
MIR Pro is not "another reverb" you just add to an existing mix. It is a complete tool for spatialization, taking into account a huge set of variables, not just reverb. When you move away from a signal source in reality, its direct signal will get lower in volume. MIR Pro takes care for that, as long as you don't switch off that behavior deliberately (by means of the "Distance Dependent Scaling" option). As soon as the signal source is turning away from you, its sound will change as well as the perceived volume (in most cases). So it's quite usual that you will see different levels from a mix done within MIR Pro than you've had before.
That said, I suspect that you were using the Natural Volume feature when selecting the Instrument Profiles. This feature is meant to make an initial setup easy by suggesting typical volumes for each Vienna Instrument. You have to keep in mind that a few instruments in a full-blown modern orchestra can get very loud, though, that's why most others have to be lowered in volume considerably, to allow for enough headroom. If you find that you don't need this headroom, just select all Icons on a MIR Venue's stage and raise all individual volumes simultaneously by holding ALT.
(Side-note: By using MIR Pro within VE Pro, you could also route all signals to a common bus channel and raise the volume there).
I don't know about a volume offset slider - could it be that you're simply misinterpreting the volume control for MIR Pro's Room Tone? This feature is explained on p. 47 of MIR Pro's preliminary manual. - When working with MIR Pro's plug-in version, you will have to dedicate one channel for the Room Tone's output.
HTH,
Thanks Dietz. For sure I understand that's it not just another reverb (that's why I'm trying it!), I was hoping there was a volume compensation mechanism built-in to MIR to help with this (as opposed to inserting a Gain plug-in in Logic and boosting it 12 db). I will try deselecting Natural Volume, thanks. And yes, I mistakenly thought at quick glance that the secondary mic slider might be what I was looking for. As for Room Tone, I've been looking at the manual but I'm just not understanding exactly what it is as relates to MIR in general -- isn't the "room" already part of the impulses? So, by your response, since I will always be using MIR as a plug-in, I'll need to dedicate a channel for room tone (not sure how to do this, but will look for the answer in the manual again). Thanks for your help, and great product!
Re: Natural Volume: This is just a predefined volume setting, no need to deselect it. The button will become unlit as soon as you move an Icon's volume fader manually. - BTW - there's an option inside MIR Pro's Preferences which defines whether Natural Volume should be active by default or not.
Re: Room Tone: What we call Room Tone is simply the natural noise floor of each hall we captured for MIR Pro. Why would you need this? In reality, there's no "absolute silence" - the reverb of any signal wouldn't end in "cold digital black" like it would in case of an impulse response, which is of finite length, of course. - By adding the natural noise of a hall, the IR smoothly "lands" in the faint, but omnipresent noise.
For adding the Room Tone to a project based on MIR Pro's plug-in version (opposed to the VE Pro based stand-alone version), you just have to add an empty channel to your Logic project; insert the MIR Pro plug-in there, and click the button labeled "RT". This channel now will contain the Room Tone of the chosen Venue, according to the chosen Output Format. - The formerly grayed-out Room Tone Volume Fader in MIR Pro's main GUI will now be active.
HTH,
